RESEARCH: My research and
that of my students centers around fish and mussel ecology, biotic interactions, and impacts of habitat
and environmental alterations associated with global change -- especially
in the stream environment. The main emphasis of this work is in
identifying physical and biotic influences on the ecological
success of aquatic fauna at multiple spatial, temporal, and organizational
scales and quantifying such relationships. This includes studies of
population and production dynamics, community interactions, habitat assessment and
manipulation, ecotoxicology, food-web functions, density-dependent effects, and
empirical and simulation modeling. In addition to many sampling and
parameter-estimating techniques, we've incorporated biotelemetry,
automated antenna arrays, geographic information systems, stable
isotope composition, contaminant analyses and bioassays, otolith structure and microchemistry, and software development into our research. The ultimate goal of this effort is to incorporate our science into
sound ecosystem and fisheries conservation and management.
